Convert

ipv6 :: Word16 -> Word16 -> Word16 -> Word16 -> Word16 -> Word16 -> Word16 -> Word16 -> IPv6

Create an IPv6 address from the eight 16-bit fragments that make it up. This closely resembles the standard IPv6 notation, so is used for the Show instance. Note that this lacks the formatting feature for suppress zeroes in an IPv6 address, but it should be readable enough for hacking in GHCi.

>>> let addr = ipv6 0x3124 0x0 0x0 0xDEAD 0xCAFE 0xFF 0xFE00 0x1
>>> addr
ipv6 0x3124 0x0000 0x0000 0xdead 0xcafe 0x00ff 0xfe00 0x0001
>>> T.putStrLn (encode addr)
3124::dead:cafe:ff:fe00:1

fromOctets :: Word8 -> Word8 -> Word8 -> Word8 -> Word8 -> Word8 -> Word8 -> Word8 -> Word8 -> Word8 -> Word8 -> Word8 -> Word8 -> Word8 -> Word8 -> Word8 -> IPv6

fromWord16s :: Word16 -> Word16 -> Word16 -> Word16 -> Word16 -> Word16 -> Word16 -> Word16 -> IPv6

An alias for the ipv6 smart constructor.

fromWord32s :: Word32 -> Word32 -> Word32 -> Word32 -> IPv6

Build an IPv6 from four 32-bit words. The leftmost argument is the high word and the rightword is the low word.

fromTupleWord16s :: (Word16, Word16, Word16, Word16, Word16, Word16, Word16, Word16) -> IPv6

Uncurried variant of fromWord16s.

fromTupleWord32s :: (Word32, Word32, Word32, Word32) -> IPv6

Uncurried variant of fromWord32s.

toWord16s :: IPv6 -> (Word16, Word16, Word16, Word16, Word16, Word16, Word16, Word16)

Convert an IPv6 to eight 16-bit words.

toWord32s :: IPv6 -> (Word32, Word32, Word32, Word32)

Convert an IPv6 to four 32-bit words.

Special IP Addresses

any :: IPv6

loopback :: IPv6

Textual Conversion

Text

encode :: IPv6 -> Text

Encodes the IP, using zero-compression on the leftmost-longest string of zeroes in the address. Per RFC 5952 Section 5, this uses mixed notation when encoding an IPv4-mapped IPv6 address:

>>> T.putStrLn $ encode $ fromWord16s 0xDEAD 0xBEEF 0x0 0x0 0x0 0x0 0x0 0x1234
dead:beef::1234
>>> T.putStrLn $ encode $ fromWord16s 0x0 0x0 0x0 0x0 0x0 0xFFFF 0x6437 0xA5B4
::ffff:100.55.165.180
>>> T.putStrLn $ encode $ fromWord16s 0x0 0x0 0x0 0x0 0x0 0x0 0x0 0x0
::

decode :: Text -> Maybe IPv6

Decode an IPv6 address. This accepts both standard IPv6 notation (with zero compression) and mixed notation for IPv4-mapped IPv6 addresses.

parser :: Parser IPv6

Printing

print :: IPv6 -> IO ()
